Benefits of technology

[0009] The present relates to a device for tissue-characterization, designed for effective sensor-to-tissue contact. The device includes an element, having a rigid surface of a linear cross-section, on which at least one sensor is arranged, and a mechanism for applying a force to a soft tissue, the line of force being at an acute angle with the rigid surface, for stretching or stretching and pushing...

Problems solved by technology

For example, the presence of air bubbles between an ultrasound sensor and the tissue will interfere with ultrasound measurements.
Similarly, a liquid layer may inte...

Embodiment Construction

[0149] The present invention relates to a device for tissue-characterization, designed for effective sensor-to-tissue contact. The device includes an element, having a rigid surface of a linear cross-section, on which at least one sensor is arranged, and a mechanism for applying a force to a soft tissue, the line of force being at an acute angle with the rigid surface, for stretching or stretching and pushing the soft tissue against the rigid surface, thus achieving effective contact between the tissue and the at least one sensor. In consequence, the accuracy of the sensing is improved. In accordance with another embodiment, a plurality of sensors is employed, arranged along a curved element, for providing three-dimensional information regarding the tissue, for example, by small-scale computerized tomography.

[0150] Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of const...

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present invention is a continuation in part of U.S. patent application Ser. No. 11 / 196,732, filed on Aug. 4, 2005, whose disclosure is incorporated herein by reference.FIELD AND BACKGROUND OF THE INVENTION [0002] The present invention relates to local tissue characterization and more particularly, to a tissue-characterization probe with effective sensor-to-tissue contact. The probe is further adapted for providing three-dimensional information. [0003] A large number of techniques and sensors are available today for tissue characterization, for example, to determine the presence of abnormal tissue, such as cancerous or pre-cancerous tissue. These may be incorporated into hand-held probes or miniature probes, adapted for insertion into a body lumen or for use in minimally invasive surgery. While the operating principles of different tissue characterization sensors differ, effective contact between the sensor and the tissue is often es...
